Abstract

An educational interlocking block set having six facing sides. Two of the opposite block sides have either a four spaced projecting male protrusions or a four spaced complimentarily shaped receiving female recesses for male protrusions of an adjoining interconnected block. The other four sides of each block may have the same letter thereon to permit the viewing of their displayed surfaces. When several interlocked blocks are viewed, either in horizontal or vertical configurations, words may be spelled out by the displayed letters of the blocks. Vertically aligned blocks may be either stacked upon joined lower horizontally disposed blocks or may be joined vertically thereto. An almost endless configuration of joined blocks representing different joined shapes, such as pyramids and diamonds, may be constructed with visible surface letters.

What I claim as my invention is: 
     
       1. An educational interconnecting block set comprising: a plurality of interconnectable blocks,   each of said blocks having six facing side surfaces, one of said side surfaces having four spaced projecting frusto-conical shaped male protrusions whose diameter deceases as the protrusion distance increases from the supporting facing block side surface, four complimentarily shaped and spaced female recesses on the opposite side surface of the block side surface with said protrusions, said female recesses each being capable of receiving a male protrusion from a different adjoining block with four similarly shaped and spaced frusto-conical shaped protrusions; and   each of said blocks having letter indicia on each of the four facing block side surfaces without said four frusto-conical spaced protrusions or said four female recesses.   
     
     
       2. The educational interconnecting block set of claim 1 wherein said letter indicia on each of said four facing block sides is the same letter on each side.
